[0026] Reference Figure 1-5A clamping and positioning assembly suitable for drilling holes in aluminum profiles comprises an operating table 1, a connecting frame 2 is fixedly installed on the surface of the operating table 1, a pressure rod 5 is slidably connected inside the connecting frame 2, a pressure ring 6 is fixedly installed on the port of the pressure rod 5, a driving structure for driving the pressure rod 5 to slide in the vertical direction is provided on the surface of the connecting frame 2, long rods 7 are fixedly installed on both sides of the pressure ring 6, connecting rods 8 are slidably connected on the surfaces of the two long rods 7, cylinders 9 are fixedly installed on the tops of the two connecting rods 8, a connecting block 10 is fixedly installed on the output end port of the cylinder 9, the connecting block 10 and the connecting rod 8 are slidably connected, two pressure strips 12 are slidably connected to the side wall of the connecting block 10, a gear 11 is rotatably connected to the side wall of the connecting block 10, the gear 11 and the pressure strips 12 on both sides are meshed, a limiting structure for limiting the sliding of the connecting rod 8 is provided on the surface of the two long rods 7, when in use, the aluminum material is placed on the surface of the operating table 1, the pressure rod 5 is driven downward by the driving structure, and the pressure rod 5 moves downward. The movement drives the pressure ring 6 to move downward, and the pressure ring 6 moves downward to squeeze and fix the aluminum part, and the position to be punched is just located at the center of the pressure ring 6, slide the two connecting rods 8, move the two connecting rods 8 to the appropriate position, and use the limiting structure to limit it so that it can no longer slide, and then start the two cylinders 9, the two cylinders 9 drive the two connecting blocks 10 to move downward, and the connecting blocks 10 drive the pressure strip 12 to move downward. When one of the pressure strips 12 contacts the surface of the aluminum part, the pressure strip 12 will not continue to move, and the cylinder 9 continues to press down. At this time, the gear 11 starts to rotate, and the rotation of the gear 11 drives the other pressure strip 12 that does not contact the surface of the aluminum part to move downward. When the other pressure strip 12 contacts the surface of the aluminum part, the gear 11 will be restricted and stop rotating. At this time, the gear 11 will squeeze the two pressure strips 12 at the same time, so that the irregular aluminum part is squeezed and fixed on the surface of the operating table 1 by the rack, which is convenient for drilling holes in the aluminum part, with better fixing effect, less prone to position displacement, and convenient for practical use.

[0027] Furthermore, the driving structure includes a screw 3, which is rotatably inserted into the interior of the connecting frame 2. The screw 3 threadably penetrates the pressure rod 5. A turning handle 4 is fixedly installed at the end of the screw 3 away from the operating table 1. When the driving structure is in use, the handle is turned, and the handle drives the screw 3 to rotate. The rotation of the screw 3 drives the pressure rod 5 to move downward, so that the pressure rod 5 drives the pressure ring 6 to move downward to extrude and fix the aluminum part on the surface of the operating table 1, which is convenient for practical use.

[0028] Furthermore, the thickness of the pressing ring 6 is greater than that of the pressing rod 5 so that when the bottom of the pressing ring 6 contacts the workpiece, the pressing rod 5 does not contact the workpiece. The thickness of the pressing ring 6 is greater than that of the pressing rod 5 so that the pressing ring 6 contacts the irregular aluminum part, and the pressing ring 6 can contact the aluminum material, avoiding the influence of the pressing rod 5 and failing to achieve the effect of extrusion and fixing.

[0029] Furthermore, the limiting structure includes a limiting frame 13, which is an "n"-shaped structure. The limiting frame 13 is slidably connected to the connecting rod 8. The limiting rod 15 and the spring 14 are fixedly installed on the side where the two arms of the limiting frame 13 are close to each other. The other end of the spring 14 is fixedly connected to the connecting rod 8. The side wall of the long rod 7 is evenly provided with limiting holes that are compatible with the size of the limiting rod 15. When the limiting structure is in use, one side of the limiting frame 13 is pressed to compress the spring 14. At this time, the limiting frame 13 slides toward the outside of the connecting rod 8, so that the limiting frame 13 drives the limiting rod 15 away from the limiting hole, so that the connecting rod 8 is no longer restricted and can slide left and right in the horizontal direction. When it moves to the appropriate position, the limiting frame 13 is released. Under the action of the spring 14, the limiting frame 13 slides toward the inside of the connecting rod 8, so that the limiting rod 15 is stuck in the limiting hole, so that the connecting rod 8 cannot slide, which is convenient for position adjustment according to the size of the aluminum part and is convenient for practical use.

[0030] Furthermore, a sliding groove is provided on the surface of the connecting rod 8, and the connecting block 10 is slidably connected to the connecting rod 8 by means of the sliding groove. By providing the sliding groove, the sliding between the connecting rod 8 and the connecting block 10 is more stable, thereby improving the fixing effect.

[0031] Furthermore, a long groove is provided on the surface of the connecting frame 2, the screw rod 3 is rotatably connected inside the long groove, and the pressure rod 5 is slidably connected to the long groove. By providing the long groove, the operation of the pressure plate in the vertical direction is more stable.

[0032] In summary, when in use, the aluminum material is placed on the surface of the operating table 1, and the driving structure is used to drive the pressure rod 5 to move downward, and the pressure rod 5 moves downward to drive the pressure ring 6 to move downward, and the pressure ring 6 moves downward to squeeze and fix the aluminum part, and the position to be punched is just located at the center of the pressure ring 6, and the two connecting rods 8 are slid, and the two connecting rods 8 are moved to a suitable position and restricted by the restriction structure so that they can no longer slide, and then the two cylinders 9 are started, and the two cylinders 9 drive the two connecting blocks 10 to move downward, and the connecting blocks 10 drive the pressure strips 12 to move downward. When one of the pressure strips 12 contacts the surface of the aluminum part, the pressure strip 12 will not continue to move, and the cylinder 9 continues to press downward. At this time, the gear 11 When the gear 11 starts to rotate, the gear 11 rotates to drive the other pressure strip 12 that is not in contact with the surface of the aluminum part to move downward. When the other pressure strip 12 contacts the surface of the aluminum part, the gear 11 will be restricted and stop rotating. At this time, the gear 11 will squeeze the two pressure strips 12 at the same time, so that the irregular aluminum part is squeezed and fixed on the surface of the operating table 1 by using the rack, which is convenient for drilling holes in the aluminum part, with better fixing effect, less prone to position deviation, and convenient for practical use. When the driving structure is in use, the handle is turned, and the handle drives the screw 3 to rotate. The rotation of the screw 3 drives the pressure rod 5 to move downward, so that the pressure rod 5 drives the pressure ring 6 to move downward to squeeze and fix the aluminum part on the surface of the operating table 1. In actual use, the thickness of the pressing ring 6 is greater than the thickness of the pressing rod 5 so that the pressing ring 6 contacts the irregular aluminum part, which can make the pressing ring 6 contact the aluminum material and avoid being affected by the pressing rod 5 and failing to achieve the effect of extrusion and fixing. When the limiting structure is in use, one side of the limiting frame 13 is pressed to compress the spring 14. At this time, the limiting frame 13 slides to the outside of the connecting rod 8, so that the limiting frame 13 drives the limiting rod 15 away from the limiting hole, so that the connecting rod 8 is no longer restricted and can slide left and right in the horizontal direction. When it moves to the appropriate position, the limiting frame 13 is released. Under the action of the spring 14, the limiting frame 13 slides to the inside of the connecting rod 8, so that the limiting rod 15 is stuck in the limiting hole. In this way, the connecting rod 8 cannot slide, which makes it convenient to adjust the position according to the size of the aluminum part and is convenient for practical use. By setting the slide groove, the sliding between the connecting rod 8 and the connecting block 10 is more stable, which improves the fixing effect. By setting the long groove, the operation of the pressure plate in the vertical direction is more stable. By setting the pressure plate, pressure ring 6, connecting rod 8, cylinder 9, gear 11, pressure strip 12 and other structures, irregular aluminum parts can be squeezed and fixed when holes are cut, which enhances the stability when cutting holes. Moreover, the position of the cut hole is squeezed and fixed by the pressure ring 6, and the position of the cut hole is just inside the pressure ring 6, which improves the accuracy of the cut hole and is convenient for practical use.
